( Brand: Ge ), ( Model: VT-4C / 211 ), ( Type: Vacuum Tube ), ( Country/region Of Manufacture: United States )
The VT-4C radio transmitting tube, manufactured by General Electric under their 211 series, is a vital component in various radio transmitter applications. This tube, specifically the VT-4C, is a triode vacuum tube that operates in the high frequency range, making it ideal for use in radio transmitters.
The VT-4C tube features a triode configuration, which means it has three electrodes: the cathode, grid, and plate. The cathode emits electrons, the grid controls the flow of these electrons, and the plate collects the electrons. This configuration allows for precise control of the current flow, enabling the tube to amplify weak radio signals and transmit them with power.
The VT-4C tube is designed to operate at a frequency range of approximately 45 to 50 MHz. This high-frequency operation allows it to transmit radio waves efficiently, making it suitable for applications such as FM radio broadcasting. The tube's high power handling capability, typically up to 15 watts, ensures it can deliver sufficient power to transmit strong, clear radio signals over long distances.
Physically, the VT-4C tube is a cylindrical device with a glass envelope. Inside this envelope, the filament, grid, and plate are housed. The filament is a small wire that heats up to emit electrons, the grid is a metal mesh, and the plate is a large metal plate. The tube is typically connected to an external power supply and a radio transmitter circuit to function.
In summary, the VT-4C radio transmitting tube is a crucial component in radio transmitter applications. Its triode configuration, high-frequency operation, and high power handling capability make it an excellent choice for FM radio broadcasting. The VT-4C tube, manufactured by General Electric as part of their 211 series, is a reliable and efficient solution for transmitting clear, strong radio signals over long distances.
